Artificial fibers

Nzira yekugadzirira
Iwo maviri makuru manyuko erayon ipetroleum uye biological masosi.Regenerated fiber rayon yakagadzirwa kubva kubiological sources.Maitiro ekugadzira mucilage anotanga nekutorwa kweiyo pure alpha-cellulose (inozivikanwawo sepulp) kubva kune yakabikwa cellulose zvinhu.Iyi pulp inobva yagadziriswa ne caustic soda uye carbon disulfide kuti ibudise orange-colored cellulose sodium xanthate, iyo inobva yanyungudutswa mu diluted sodium hydroxide solution.Iyo coagulation yekugezera inoumbwa ne sulfuric acid, sodium sulfate, uye zinc sulfate, uye mucilage inosefa, ichipiswa (inoiswa pane yakatarwa tembiricha kweanenge 18 kusvika maawa makumi matatu kuderedza esterification ye cellulose xanthate), yakasvibiswa, uye yobva yanyorova. spun.Mukugezera kwekugezera, iyo sodium cellulose xanthate inoora ne sulfuric acid, zvichiita kuti cellulose ivandudzwe, kunaya, uye kusikwa kwe cellulose fiber.

Classification Sirika yakapfuma, shinda yakaoma, shinda yeminhenga, sirika yekugadzira isina kupenya

Zvakanakira
Iine hydrophilic hunhu (11% mwando kudzoka), viscose rayon ndeyepakati kune inorema basa jira rine rakajairwa kune yakanaka simba uye abrasion kuramba.Nekutarisirwa kwakakodzera, fiber iyi inogona kucheneswa yakaoma uye kugezwa mumvura isina static magetsi kana mapiritsi, uye haina kudhura.

Zvakaipa
Rayon's elasticity uye kusimba haina kunaka, inoderera zvakanyanya mushure mekugezwa, uye zvakare inotapukirwa nekuumbwa nekuvhuvhu.Rayon inorasikirwa ne30% kusvika 50% yesimba rayo kana yanyorova, saka kungwarira kunofanirwa kutorwa pakugeza.Mushure mekuoma, simba rinodzorerwa (rakavandudzwa viscose rayon - high wet modulus (HWM) viscose fiber, hapana dambudziko rakadaro).

Uses
Zvikumbiro zvekupedzisira zverayon zviri muminda yezvipfeko, upholstery, uye indasitiri.Mienzaniso inosanganisira matop evakadzi, hembe, hanzu dzemukati, mabhachi, machira anorembera, mishonga yemishonga, nonwovens, uye zvinhu zvehutsanana.

Kusiyana pakati perayon
Artificial Silk ine sheen inopenya, yakaonda zvishoma uye yakaoma, pamwe nekunyorova uye kutonhora kunzwa.Kana yakaunyana uye isina kukwizwa neruoko, inoita mikunya yakawanda.Kana yati sandara, inochengeta mitsetse.Kana kuguma kwerurimi kwakanyoroveswa uye kushandiswa kuburitsa jira, sirika yekugadzira inotwasanudza nyore uye inoputsika.Kana yakaoma kana kunyorova, elasticity inosiyana.Kana zvidimbu zviviri zvesirika zvinokwizwa pamwe chete, zvinogona kuita ruzha rwakasiyana.Sirika inozivikanwawo se "sirika," uye kana yakakoshwa yobva yaburitswa, makwinya anoita kushomeka.Zvigadzirwa zveSirika zvakare zvine zvese zvakawoma uye zvakanyorova elasticity.
